DICE

DICE is a Discrete Integrated Circuit Emulator. It emulates computer systems that lack any type of CPU, consisting only of discrete logic components.

It was first released in 2008 as a circuit-level simulation of Pong. libretro: dice is a libretro port.

This system scrapes metadata for the “dice, arcade” group(s) and loads the dice set from the currently selected theme, if available.

Quick reference

BIOS

No DICE emulator in Batocera needs a BIOS file to run.

ROMs

Place your DICE ROMs in /userdata/roms/dice.

Games without any ROM component use .dmy files as dummy launchers. Some games (pong, breakout, pinpong, etc) do not have any ROM on the board at all. For these, copy the dummy launcher file from dummy_files to your ROM folder; these have a correct name (for example, pong.dmy) that will get RetroArch to set up lr-dice for the correct game.

You can find DIP switch values at DIP Switches.

Controls

Here are the default DICE controls shown on a Batocera RetroPad:

DICE also supports one or several mice or mice-like spinners as paddle controllers:

  • Easy: One mouse can be used for Paddle 1. Use ADVANCED GAME OPTIONS → CONTROLS → USE MOUSE POINTER FOR PADDLE 1. You'll still want a keyboard or gamepad handy to have enough buttons.
  • Somewhat advanced: Multiple mice are supported using Batocera's input drivers, see retromouse.md and use ADVANCED GAME OPTIONS → CONTROLS → USE MOUSE FOR PADDLE 1 and similar in EmulationStation to set options.

Troubleshooting

Vertical games like Breakout and Pin Pong are stretched

Set ADVANCED GAME OPTIONS → GAME ASPECT RATIO → CORE PROVIDED for these games.

This is more likely with non-default bezels.

Further troubleshooting

For further troubleshooting, refer to the generic support pages.
